Baller Black

This patch is used to control the servo motor of cnc.

I made a black line to walk randomly in the LCD.

Can it walk only in irregular shape areas, such as pink triangles?

Or when black lines pass through different color areas, there will be different signal outputs.

If I can, I will be able to set different color areas on the LOD so that the black lines can walk in the designated area.

  I’m a beginner, ask everyone

interesting problem. I found this which might be of help:

if you are only using triangles try the barycentric coordinate system to determine if the a point in time is inside or outside the triangle

here's one approach to one aspect of your problem(s):

it only works with triangles though. It may be of help if you can make the line change direction when it goes outside of the boundary

fantastic, so amazing. let me take some time to study it. thank you very much.

here's another way of checking if a point is inside or outside. This works for any polygon, not just triangles:
